Abstract

Laser imaging techniques based on Lorenz-Mie, Rayleigh, fluorescence, and Raman scattering are productive tools for studying turbulent reacting and nonreacting flows. Using these techniques, two-dimensional measurements of temperature, species concentration, and density have been demonstrated. By simultaneously utilizing multiple scattering mechanisms, the basic laser imaging configuration can be extended to allow derivation of quantities that are important for modeling turbulent flames. Two examples of experiments of this type will be presented. In each experiment, two different light scattering mechanisms are monitored using separate detectors (see Fig. 1).
